The Ukrainian authority sent their Russian counterparts diplomatic note but received no answer so far

‘On October 2, as soon as we learned about Susuchenko’s detention, our consulate division sent a letter urging to organize the meeting for Sushchenko and the Ukrainian consul in Russia. On October 3, the consul personally handed the note to the FSB, Russian federal security service. The same day, our Embassy in Russia sent the respective note to the Russian Foreign Ministry’. Maryana Betsa, the spokeswoman for Ukraine’s foreign ministry, said this as quoted by Ukrainska Pravda outlet.

The world's largest organization of media professionals International Federation of Journalists (IFJ) and its subsidiaries in Europe (EFJ) have also urged the Russian Federation to release Ukrainian journalist Roman Sushchenko.
